Before and after photos of Fourmile Creek near Ankeny, Iowa, showing a wastewater outfall from a wastewater treatment facility (WWTF). The top photo is the creek before the WWTFwas closed, and the bottom photo is after the WWTF was shutdown. After the shutdown flow in the creek decreased significantly. Photo credits: Laura E.

Western view toward the Red Mountains near Silverton, Colorado, taken just upstream from the North Fork Cement Creek drainage in 2006. The photo illustrates acidic drainage (red drainage at right) and less acidic drainage (white drainage at left of photo) that originates from altered rocks and mines in the watershed.
